Newtonian physics and relativity differ in their treatment of motion and gravity. Newtonian physics describes motion and gravity based on absolute space and time, while relativity considers them as relative and interconnected. Additionally, relativity accounts for the effects of high speeds and strong gravitational fields, which are not addressed in Newtonian physics.
Newtonian physics, developed by Sir Isaac Newton, describes the motion of objects in the everyday world using concepts like force, mass, and acceleration. It is based on absolute space and time. Einsteinian physics, or the theory of relativity, developed by Albert Einstein, revolutionized our understanding of space and time. It describes how gravity affects the fabric of spacetime and how objects move in relation to each other. It is based on the idea that space and time are relative and interconnected. The key differences between the two are in their treatment of space, time, and gravity. Newtonian physics is a simpler, more intuitive description of motion, while Einsteinian physics provides a more accurate and comprehensive understanding of the universe.
Einstein's inspiration for developing the theory of relativity came from trying to reconcile inconsistencies between Newtonian physics and the behavior of light. His curiosity about the nature of time and space, combined with his dissatisfaction with existing theories, led him to develop the groundbreaking ideas of special and general relativity.
Einstein's theory of relativity replaced the classical Newtonian view of absolute space and time. Instead of being fixed and independent, space and time in Einstein's theory are intertwined and can be different depending on the observer's motion.
The behavior of particles at very high speeds or very small scales is best described by the principles of relativity and uncertainty rather than classical Newtonian physics. Relativity allows for predictions about motion at relativistic speeds, while uncertainty provides a framework for understanding the inherent randomness in the behavior of subatomic particles.
Classical physics refers to the physics developed before the advent of quantum mechanics and relativity, focusing on the behavior of macroscopic objects in everyday conditions. It includes Newtonian mechanics, thermodynamics, and electromagnetism, providing a framework for understanding motion, energy, and forces at a larger scale.

Typically, there are considered two forms of physics. Newtonian and modern. Newtonian relates to Newton-era mechanics and E&M. Modern physics loosely refers to post-newton physics. Modern physics primarily refers to 20th century physics as it incorporates relativity and quantum theory.
Newtonian physics, also called classical or pre-relativistic physics refer to the physics after Aristotelian physics and before the 1920s when the theory of relativity was formed. They distinctly differ from Aristotelian physics in that they cover the physics of motion, scientific method, describe contact and non-contact forces such as magnetism

Newtonian physics fails to explain motion correctly in extreme conditions such as at speeds approaching the speed of light or in the presence of very strong gravitational fields where the effects of relativity become significant. Additionally, at the quantum level, where particles behave in ways that cannot be predicted using classical physics, Newtonian physics also breaks down.

Newtonian and relativistic physics will give you the same answers if you're at small gravity/acceleration or speed. But as you approach light speed/insane gravity/insane acceleration and other insane limits and time begins to do crazy stuff, relativity begins to show the true answers and newtonian physics gets messed up. Just don't get a T.A.R.D.I.S and you'll be fine.
Einstein's general theory of relativity rendered Newtonian gravity obsolete However, the rest of Newton's work is NOT obsolete and even with gravity his equations still work OK, it is the explanation for gravity that has changed.
